Key Ingredients

You will need the following key ingredients to make this delicious breakfast recipe:

  • Rolled oats: Also called old fashioned oats, these are the best type of oats to use for this dish. Steel cut oats take longer to cook and quick oats will end up mushy, so make sure to use rolled oats!
  • Almond milk: Use any kind of milk you like, but my personal preference is unsweetened plain almond milk.
  • Bananas: When choosing your bananas, make sure to opt for the ripest ones you can find! These will not only be much easier to mash, but they will also be sweeter.
  • Maple syrup: This natural sweetener adds just the right amount of sweetness to this dish. Feel free to swap it out for honey or agave, if needed.
  • Spices: This recipe calls for a combination of vanilla extract, cinnamon, and salt to add a ton of delicious flavor to the dish.

Baked Oatmeal Recipe Tips

Here are some of my top tips and tricks to help you make this recipe:

  • For the best results, make sure to use rolled oats for this recipe. Steel cut oats take longer to cook and require a different oat to liquid ratio, while quick oats will get mushy in the oven.
  • Feel free to swap out the unsweetened almond milk for the sweetened kind or any type of milk you like.
  • If you don’t have maple syrup, you can use honey or agave syrup instead.
  • If you can’t eat eggs for any reason, feel free to simply leave the egg out or add extra chia seeds in its place.
  • Not a banana fan? Try using applesauce, mashed sweet potatoes, or pumpkin puree instead.
  • For an extra boost of protein, try adding 1-2 scoops of your favorite protein powder or a dollop of nut butter to the dish.
  • For added flavor and a stunning presentation, try garnishing the dish with tasty toppings like fresh fruit, chopped nuts, and Greek yogurt or nut butter.

What to Add to Baked Oatmeal

There are tons of options for what to add to baked oatmeal. It all depends on what you have at home and what you’re in the mood for. This recipe is super versatile, so you can go the chocolate/nut butter route or the fresh fruit route. You could even add them all!

It’s entirely up to you, so don’t be afraid to get creative. If you need a little inspiration, here are some of my favorite mix-ins to add to baked oatmeal:

  • Chocolate chips or cacao nibs like in this Chocolate Baked Oatmeal.
  • Nut butter (peanut, almond, cashew, sunflower seed)
  • Fresh fruit (strawberries, blueberries, peaches, cherries)
  • Chopped nuts (almonds, pecans, walnuts, pistachios)
  • Seeds (chia seeds, hemp seeds, flax seeds, pumpkin seeds)

How to Store Leftover Baked Oatmeal

Looking for a healthy breakfast meal prep recipe? You’re in luck! This dish keeps really well both in the fridge and in the freezer. I love prepping a big batch at the beginning of the week and storing it in individual servings to munch on throughout the week. It makes for fantastic on-the-go breakfasts and easy afternoon snacks.

To store this dish, you will first need to let it cool down to room temperature. Once the oatmeal has cooled, cut it into slices and transfer it to an airtight storage bag or container. Then, you can store baked oatmeal in one of two ways:

  • In the fridge for up to 4-5 days.
  • In the freezer for up to 3 months.

Frequently Asked Questions

Below are the answers to some of the most frequently asked questions about this dish:

Yes! This dish is naturally gluten-free, dairy-free, and sugar-free. It’s made with wholesome ingredients and is loaded with fiber, protein, vitamins, and minerals. When enjoyed in moderation, this dish is a perfectly healthy addition to your diet.

When it comes to oatmeal mix-ins, you have a ton of options to choose from. Some of my favorite options include chocolate chips, nut butter, fresh fruit, dried fruit, shredded coconut, seeds, and chopped nuts.

You can swap out the almond milk for any other type of milk you prefer. Some of the most common choices include oat milk, soy milk, cashew milk, and dairy milk.

Baked oatmeal won't work with steel-cut oats since they don't cook the same way as rolled oats. The steel-cut oats won't cook through all the way and the end product will be gritty and hard. Instant oats also won't work well for this recipe since they are too mushy and cook too quickly. Old-fashioned rolled oats are the best option for making any kind of baked oatmeal.
